Tactics
When this buyer has awarded in this sector, usually 7 or more bids came in. Many compete here — price and references decide. (Based on 218 completed awards — not a statement about this procedure.)
This procedure allows 35 days between publication and deadline — typical in this country is 27 (median of 7,300 procedures). Much more generous than usual — time for a thorough bid rather than a quick one.
The deadline falls on a Monday — your last full working day is the Friday before. Have evidence and guarantees together by Thursday.
